Hey there, I had a question about old substrate. Its been sitting by the side of my house outside for about 5 months. If I rinse it out real good could I use it again. I wanted to use some for my new 10 gallon tank. And sterilizing in the oven is out of the question, my mom would kill me. thx

It's pretty much inert, so sitting outside isn't going to really do much to it. (barring exposure to pesticides, soap/detergent, petrochemicals, etc.)

I wouldn't even worry about sterilizing it, I doubt it would pick up much harmful to a fish in a terrestrial environment. - just give it a good rinsing to get out any dust/bugs/debris that may have accumulated
